Debugging a Dll used by an application

I have an application that uses a dll.  They are both in the same solution.  I am having a problem setting break points inside the dll and debugging it.  Thanks guys.  I've seen some of the documentation but still hitting a wall.  Thanks.

1. ensure that both projects are built in debug mode, and both are build with compatible options (Debug MT is incompatible with Debug MT DLL)
2. mark the DLL project as a startup project
3. set executable name (Debugging/Command) for DLL project from EXE project
4. set breakpoints in DLL project
5. run

I have to do this from the exe side.  There are configuration files located in that directory that won't be seen from the dll side.

Actually that will work.  There are only 3 files that I need. I'll just copy them into the start up folder.  Thanks.  But could you tell me who to do the same thing from the exe side?

The application launches like it should but the break points are not setting.
JIEXACommented:
You can tell in the Debugging what's the start directory for the DLL.
Again: the startup project is of the DLL, not the EXE.
DanRollinsCommented:
I seem to recall having this problem at one point, and solved it by breakpointing early in the EXE.  As soon as the EXE was in debug mode, I could then breaakpoint the DLL (and/or single-step into it).

But it shouldn't be necessary to do it that way... if the DLL is marked as a dependancy of the EXE, VS should accept breakpoints in it.

Set the Debug option "Debug Type" to mixed for both projects and vowala.

this will work but it wasn't the cleanest.
